@Pinocchio @Aldo Marchand @Ayla Thank you for the replies of all three of you. I want to respond to that. I know I only hurt myself Ayla. Like the Buddha said: "Holding on to anger is like holding on to a hot coal; you want to hurt someone else but in the end only you get burned". And Aldo, sometimes it helps to just focus on the future and not think about petty things of the past. But in this cases (there are more) I have trouble accepting it. And Pinocchio, I know I must not take it personally. Eckhart Tolle has some excellent videos on not to take things personally because in this specific case, the landlord did not do anything to my ego, but he is just acting according to his (low) level of consciousness. As Eckhart would say. Eckhart says that you must not take it personally and thus do no get angry. However, he points out that you can take the appropriate action (without anger). I think I did that, the appropriate action. But still my ego feels damaged like I were a push-over. It is very hard to let this go. So yes indeed. I think it is my self-image that gets hurt. Any tips on how I can learn to see through these things and sop taking things personally? What efforts must I do? Thanks again for your responses!
